Abstract
The utility model discloses a medium voltage switchgear emergency trip push rod stroke amplification device, including a trip rotation convex button and a drivable rotation device. A moving plate is movably mounted on the drivable rotation device. A gear shaft is fixedly mounted on the moving plate. A moving gear is sleeved on the gear shaft. A stationary rack is fixedly disposed on the drivable rotation device. A moving rack is flexibly mounted on the drivable rotation device. The moving gear is engaged with the stationary rack and the moving rack to form a double gear rack pair. One end of the push rod is fixed on the moving rack. Both ends of a tension spring are respectively fixed on the drivable rotation device and the moving plate. The medium voltage switchgear emergency trip push rod stroke amplification device has the characteristics of simplifying an emergency trip assembly adjustment procedure of a breaker, improving the processing speed of breaker emergency trip, high use performance, wide application range, simple operation and reliable work.
Description
Technical field
The utility model belongs to power transmission and distribution voltage switchgear technical field, especially relates to the urgent separating brake lift rod stroke of a kind of medium voltage switchgear equipment amplifying device.
Background technology
Existing metal-clad moveable formula medium voltage switchgear equipment, after circuit breaker cart shakes and proceeds to the service position, if taking place, emergency need use urgent switching-off device to make circuit breaker separating brake power failure at once, because existing circuit breaker kind model is more, specification differs, circuit breaker end face to urgent separating brake push rod distance differs, the urgent protruding button stroke of switching-off device is because the less push rod displacement that causes of structural limitations displacement is less, in order to realize the urgent separating brake of various circuit breakers reliably, can only adopt at erecting yard and solve the effort of taking a lot of work with the method for adjusting push rod length.
Summary of the invention
The purpose of this utility model is to improve the deficiency of prior art and provides a kind of urgent separating brake assembling adjustment program, the raising that can simplify circuit breaker that the urgent separating brake of circuit breaker is disposed speed, serviceability height, the urgent separating brake lift rod stroke of scope of application medium voltage switchgear equipment big, simple to operate, reliable operation amplifying device.
The purpose of this utility model is to realize like this, the urgent separating brake lift rod stroke of a kind of medium voltage switchgear equipment amplifying device, comprise that separating brake rotates protruding button and can drive rotary body device, being characterized in that movable plate is movably arranged on can drive on the rotary body device, gear shaft is fixedly mounted on the movable plate, carrier wheel is sleeved on the gear shaft, stationary rack is fixedly mounted on and can drives on the rotary body device, mobile rack is movably arranged on and can drives on the rotary body device, carrier wheel and stationary rack, the bidentate rack-and-pinion is formed in the mobile rack engagement, push rod one end is fixed on the mobile rack, and the two ends of extension spring are separately fixed at and can drive on rotary body device and the movable plate.
In order further to realize the purpose of this utility model, can be to have strip hole on the two ends of movable plate and the mobile rack, movable plate and mobile rack are by being installed in the strip hole inner bolt and can driving rotary body device and be connected.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is that movable plate is movably arranged on and can drives on the rotary body device, gear shaft is fixedly mounted on the movable plate, carrier wheel is sleeved on the gear shaft, stationary rack is fixedly mounted on and can drives on the rotary body device, mobile rack is movably arranged on and can drives on the rotary body device, carrier wheel and stationary rack, the bidentate rack-and-pinion is formed in the mobile rack engagement, push rod one end is fixed on the mobile rack, the two ends of extension spring are separately fixed at and can drive on rotary body device and the movable plate, when pressing the protruding button of rotation, the movable plate that its other end bulb promotes to be in contact with it moves with gear shaft and the carrier wheel of movable set on gear shaft that identical speed V and identical displacement S drive on it, carrier wheel rotates under the effect of stationary rack simultaneously, drive mobile rack with the speed displacement 2S of 2V, namely move double distance with double speed, mobile rack drives push rod on it again with the speed of 2V and the displacement movement of 2S, realized the stroke amplification, realize the bigger movement of mechanism's push rod with less operational motion, adapted to polytypic, the urgent separating brake demand of the circuit breaker of many specifications, reduced the assembling adjustment time, improved operating efficiency, realized the urgent separating brake disposal of raising circuit breaker speed, serviceability improves, the scope of application is big, simple to operate, the characteristics of reliable operation, after unclamping the protruding button of rotation, movable plate resets under the effect of extension spring, drives carrier wheel simultaneously, gear shaft, mobile rack, push rod resets; The two ends of movable plate and mobile rack have strip hole, movable plate and mobile rack are by being installed in the strip hole inner bolt and can driving rotary body device and be connected, by having bolts location, the orientation on the face of cylinder with two, guaranteed the accurate engagement of gear, tooth bar and steadily mobile.
